Lim Boon Keong v Public Prosecutor: Norketamine Consumption & Drug Law Compliance
Lim Boon Keong appealed to the High Court of Singapore against his conviction in the District Court for consuming norketamine under the Misuse of Drugs Act. The High Court, presided over by Steven Chong J, allowed the appeal, finding that the prosecution's evidence was insufficient to prove beyond a reasonable doubt that norketamine was found in Lim's urine samples. The court also addressed the applicability of statutory presumptions and the evidential value of Lim's confession.
